style(copy): punctuation rules and site-wide fix with a CI check (QA U11)

- glossary: 10 punctuation rules (full-width in Chinese, CJK/Latin spacing,
  full-width parens around Chinese, single ellipsis, 「」 quotes, period rules)
- scripts/check-copy-punctuation.mjs: checks string literals, templates and JSX
  text (not comments, types, keys, match/compare strings); --fix, --strict,
  --by-file; wired into deno task ci as check:copy in warn mode
- --fix applied to web, server and contracts; files other lanes were editing
  (subscriptions, sites, browser, agent, auth/account, inventory) left for them
- tests updated for the changed messages

+| U11 | 已修 | `docs/design/glossary.md`「标点」定 10 条规范;`scripts/check-copy-punctuation.mjs` 检查字符串字面量 / 模板 / JSX 文本(不看注释、类型、对象键、匹配与比较用的字符串),接入 `deno task ci`(`check:copy`,warn 模式);`--fix` 已对 web、server、contracts 执行。订阅、站点、浏览器、Agent、认证/账户、库存相关文件当时有并行改动,未改,留给各自收尾时 `--fix` |
